Uriainal applications filed August 25, ieeaseriei a0. coasts, and March 22, 1909, serial No. 485,147. Divided and this application filed April 25, 1912. Serial No. 693,039.

To all whom it may concern: v

Be it known that l, Fneonnio W. HILLARD, a resident of Tottenville, in the county of Richmond and city and State have invented certain new and useful Improvements .inf Type-Writing which the following is a specification.

My present application is a'divisi'on o my prior application filed August 25, 1896 and serially numbered. cease, which was patented on the 30th day of April, 1912-, Patent Number 1,025,089; was divided out of said parent application in made by the "Patent Ofi ice; the subject matter here involved was then claimed in my divisional application Serial No. 485,147. filed and upon further require ment of division made therein by the Patent Oiiice-the present case was filed.

My herein invention is an improvement in larly to the Tbbon feeding, carrying an operating mechanimn. My inventipn also relates to means in a typewriting machine for feeding the printribbon by aid of mechanism provided to resolve the pull of the carriage propelling power into a component efl'ective for reciprocating the feed pawls; and also, in a visible writing typewriting machine to means 'whereby the ribbon is printing-point by'the type the carriage propelling power.

ing pawls in one direction.

reciprocated to the keys and away therefroms by aid of the repulsive action of It also relates to the combination of arepulsive escapement. with the ribbon feeding and reciprocating mechanisms; and specifically to the combination of a roller dog escapement, with said ribbon mechanisms,

whereby the repulser action of the main spring is transmitted through aid of the escapement rollerto move or reciprocate the ribbon away from the printing point and also to move or reciprocate the ribbon feed- In the accompanying drawings, which form a part of the specification: Figure 1 is a sectional elevation with some of the parts of the machine broken away or removed,

and with a portion of the ribbon vibrating I mechanism shown in full lines. Fig. 2 IS a of New York,

this application ursuance of requirement of division side elevation, showing the carriage in its raised orlifted position. Figs. 3 to 7 are positional detail views of the escapement mechanuism, which coiipe'rates with and assists in the movement of the ribbon. Figs. 3 and 6 show the parts in their normal or 4 and 7 show them in the depressed key or disengaged position; and Fig. 5 is a plan view of the'dogs and the escapement roller after the release of the depressed key, while the carriage is feeding and the dogs are being rengaged or returned to normal position;

Fig. shows a sectional view of the base frame 1. Extending in a perpendicular direction from the back portion of the base frame are the brackets 2 for the carriage guide rail 3 and the parts mounted on the guide rail. The principal parts which are mounted on machine is placed the key mounted on thebase frame of the machine. The type bar plate inclines backward at a slight angle from the perpendicular. It comprises a ring with type bars mounted concentrically thereon and pivoted so that they can all strike through the central opening 'to a common printing point on the platen 8. There is a central opening through the casing 9 which guards the type bar plate. Through this central opening the writing on the platen may be by the operator as soon as each letter has been printed.

The inking r'bbon, 10, is mounted on the spools, 11, rind is fed from one spool to the other by the ratchets, 12, and the pawls, 13, which are connected with the dog carrying rocker frame 14. There are two stationarily mounted ribbon spools, one at each side .of the machine, and likewise two ratchets and two feeding pawls,,13. Each ribbonspool is mounted to revolve, together with its ratchet, 12, on the common shaft, 15, at each side of the machine. The ribbon spool, and ratchet and their common shaft at the left hand side of the machine, are shown in dotted lines, back of the casing, 9, in Fig. 1; and the right hand ribbon clearly seen r At the spool, ratchet and shaft are shown in full lines in Fig 2.

The i so il bbon feed paWls, 13, are mounted respectively on the left hand and right hand ends of their common shaft, 16, to oscillate therewith, so that whichever pawl is in engagement with its ratchet, 12, will cause its spool shaft, 15', to revolve step by step, as the keys are operated, so as to alternately wind the ribbon first onto one spool and then the other.

Extending downwardly from rock shaft 16, there is a rocker arm, 17, in line with the dog rocker frame 1- and connected therewith by means of the connecting rod, 18, so that whenever the dog rocker is oscillated by the depression of the keys, 19, in writing, the rock shaft 16 and ribbon feed ratchet pawls, will be oscillated therewith, thus feeding the ribbon each time the keys are operated; The ribbon passes through the ribbon guide or holder, 20, and the ribbon guide is pivoted-to arm or support, 21, near its lower end, said arm being rigidly attached to the stationary machine frame, and serving as a fulcrum upon which the ribbon guide oscillates. At its lower end the ribbon guide is connected to connecting wire, 22, which latter extends back to and is connected with the dog rocker frame 14:.

The key levers, 23, are provided at their front ends with the keys 19, are fulcrumed interniediatcly on fulcrum bar 24 and the keys are normally held up by the key lever key levers underlie the universal bar, 26,

which latter is rigidly fastened on the dog rocker.

Theicarriage is mounted upon and fastened to the guide rail 3 by race ways and bearing balls in the guide rail and carriage, as shown; and it is also supported on the front rail 27, when in writing position, by means of the roller, 28. The carriage main spring is contained in the spring barrel, 28, which latter is connected to the carriage by means of connecting strap, 29. The carrings is adaptedto travel on the guide rail and front rail from one end of the rails to the other but is normally held in check by the engagement of the rack 5 with the normally engaging dog, 30.

The operation of the machine is as follows: Upon depression of a key 19, the connected type bar,'or printing member, 31, is

swung-to the platen to print, by means of the train of connections comprising, with the key lever, the key lever connecting wire, 32, bell crank, 33, and type bar connecting wire, 34:. At the same time the universal bar 26 is swung upwardly by the key lever and oscillates the dog rocker and dogs forwardly, thus disengaging the normally engaging dog 30 and engaging the normally -.ing to the printing point in Fig. 1. Upon release of the depressed key the key lever spring exerts its force to lift the key and to restore the (iOllIlOCtOCl type bar to its position of rest in the basket. lhe force of the main spring, at the same time feeding the carriage forward along the rails, causes the wing 80 of dog to run down the escapemcnt roller 37, tl 'erby swinging the escapement rocker, 1s, rearwardly and thus disengaging the dog 35from the rack and reengaging dog 30 therewith, and also, by the backward rotation of the dog rocker, swinging the ribbon carrier 20 and ribbon therein away from the printing point and out of the line of vision between the operator and the platen, as wellas assisting in lifting the depressed key and restoring the type bar into its position of rest in the basket. The force of the main spring thus applied to the escapement 'rocker, and through the rocker to the other moving parts, to restore them to their normal positions or start them back from the printing point, as above described, has come to be known in the art as repulsion; and I accordlngly use that term herein as indicatmg such impulse by thecarriage propelling power. At the same time, also, the main spring, by causing the backward oscillation of the dog rocker, oscillates the connected rocker arm and rocker bar 17, and 16, and therefore oscillates the ribbon ratchet'afeed pawls in one direction. It is thus obvious that the ribbon feed ratchet pawls are oscillated in one direction by the blow of the operator on the key and in the other direction by the force of the main spring, to feed the ribbon as the machine is operated.

I wish to call attention that in my present structure the repulsive action of the main spring may be exerted upon the type bar, at the printing point, in two Ways, after the release of the depressed key. First; it may be transmitted through the escapcment rocker to the depressed key lever and thence, through the connecting Wires 32 and 34 and the bell crank lever 38, to the short arm of the type bar which'is attached to the connecting wire 34. Or, second: it may be transmitted through the connectmg'wire 22 and ribbon holder 20 and the interposed I ribbon therein, directly to the type at the printing point. Regarding the first method of transmission it is obvious that, owing to rather acts to maintainmany of repulse ing point after the printing, to expose the feed is beginning. Such incense the several connections between the key lever and type bar in my and the necessary looseness joints, that there is liable to bee. perceptible delay in the transmission of the repulsion from the escapement to the type bar; and that this may result in the type emaining too long at the platen, while th carriage sluggishness in the the type bars from the endanger blurring in present machine,

starting away of platen will, obviously,

the print, particularly since the machine herein is a visible writing typewriter, wherein the type bars strike at the front of the platen, so that gravity does not assist instarting back the type bars from the printing point. On the contrary gravity the type bars at the platen. Regarding the second method of transmission, namely through the ribbon mechanism and ribbon directly to the type, it is-obvious that any repulsion thus transmitted will instantly start the type bar away from the platen, because there is nothin depressed key eing released before the repulsion can be. transmitted. Hence it is clear that the result which flows from my present combination of elements, is an improvement over that which would 'be obtained were the ribbon repulsion to be eliminated from the combination.

I believe myself to be broadly theifirst to have provided means whereby the force of the main spring far propelling the carriage was resolved into a component effective to the keys, and. start back the escapeand I also believe ment after the printing;

so connected up myself the first to have the ribbon reciprocating and feeding mechanisms with a repulslve escapement as that the ribbon was started away from the printwriting to view, bythe repulser action of the main spring, and also whereby the ribbon feeding pawls are reciprocated in one direction by the said repulser action.

therefore claim broadly herein, in a typewriting machine, the combination of a repulser escapement and ribbon feeding mechanism actuated thereby through the re-' pulsive component of the main spring;' and I also claim broadly herein, in a. typewriter having its printing point normally in view,

the combination with a repulser escapement,

of ribbon reciprocating mechanism, moved to the printing point by the keys, and away therefrom by aid of the repulsive component of the main spring.

In discussing the escapement mechanism herein and where I include that mechanism in the accompanying claims, I use language and terms similar tothose'used in my prior broad repulser Patent No. 580,281 patented April 6, 1897; and I intend to give such 1n the several I to. the specific .to resist such repulsion, the- -power, a

direction, and ineans operated language and terms herein thesame meaning herein as similar language comprised in said prior broad repulser patent.

Since, at the date of this application, various ribbon feeding mechanisms and in visible. writing typewriting machines, varion-s reciprocating mechanisms,..were known to the art, I do not wish; to limit ,myself mechanisms shown, ,but wish it understood that I intefi d to include in the ciaims, the variousfornis of uchmechanisrns known to the art.
